Sonji has $5.25 in nickels and dimes. The coin value can be modeled by the equation 0.10 d plus 0.05 n equals 5.25, where d represents the number of dimes and n represents the number of nickels. If Sonji has 21 dimes, how many nickels does she have?

A) 35
B) 42
C) 63
D) 105

N = 63

Step-by-step explanation:

The equation given in the question is

0.10d + 0.05n = 5.25

Putting d = 21, we get

(0.10 * 21) + 0.05n = 5.25

2.1 + 0.05n = 5.25

0.05n = 3.15

n = 63

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
